To @ZL whom t may concern.'

Be it known that I, JOHN G. PERRLN, a citizen of the United States, residing at Detroit, in 'the county ofiWayne, State of Michigan, United States of America, have invented certain 'new and Auseful Improvements in Adjustable' Lubricating Mechanism, of which the following is a specification. f Ihisin'vention relates to adjustable lubricators for engines operated at varying speeds andrelates particularly to improvements in splash lubricating system for hydro-carbon engines.

Heretofore much trouble has been experienced in properly lubricating the con- Y -necting rod crank shaft and piston vbearings '20 tity of lubricant supplied to'such bearings.

on hydro-carbon engines whichare operated at greatly varying speedsbecauseof difficulty in properly regulating the quan- The primary object -of my invention is to `provide means whereby the amount of lubricant supplied to the bearing will be automatically adjusted by the speed of the engine itself.

The further object of the invention is to accessible for the provide mechanism which shall be readily purpose of cleaning and repairing.

The various other objects of the invention will be more fully set f'orth in the following description of one form of mechanism embodying the .invention which consists in the new and novel feature of construction and combination of parts hereinafter set' forth and claimed.

Referring to the accompanying drawings: Figure 1 is a section of the bonnet and crank case of a hydro-carbon engine 'provided with my improvements. Fig. 2 represents a vertical section on the line 2-2 of Fig.'1. Fig. 3 represents a detailed view, showing the different positions of theadjustable oil trough. Fig. 4 represents a detailed plan view of the oil trough.

In the drawings only one connecting rod l is shown but it is obvious that as many connecting rods will be employed as there are cylinders on the engine connected to the crank shaft 2. The shaft is4 inclosed in a crank case 3 which is preferably provided with a bonnet 4L in the usual manner. Oil is supplied to the crank case by pipe 5 and a pipe 6 is provided whereby the bonnet and crank case can be drained. Preferably a ,I strainer isfsecured .toa shoulder formed lntegral'with the bonnet by any suitable means as the screws 8.

Arranged beneath each connecting rod and tangentially to the line of travel of the connecting rod is an open ended loiltrough 9 which is rotatably mounted at each end upon bearings formed upon a sleeve or bushing 10 secured to the bonnet and projecting a short distance within the casing. pipe .5 communicates' with the trough through one of said sleeves and provides means for supplying oil orother lubricant thereto. The trough is also provided with -a web or-flange 11 which provides means 'for the attachment of an actuating plate l2 having an arm 14 secured to Aor formed integral therewith which may be connected by any suitable means as the link 15 with the governor or throttle valve or any other moving part of the engin The arm is secured rigidly to the trough by any suitable means as the screw 16. In the particular mechanism shown inthe drawings the. rotary movement of the troughs 9 are controlled by the throttle valve ofthe engne. In this particular construction the link 15 connected to the trough is operated bythe throttle valve 18 through the fork lever 19, link 20, bell crank 21, .link'22 and arm 23, -which The latter is secured to the spindle ofthe throtcant contained in the trough, that normally falls upon and lubricates the crank shaft bearings.

In operation the oil trough, or in case a plurality of cylinders are used, all of the.

oil troughs are automatically rotated on the bearings provided by the sleeves by movement of the governor or the throttle valve or other movingpart of the engine so that when the engine is running at a low speed s the trough or troughs will be tilted and only a small quantity of the lubricant will remain therein. As the speed of the engine increases, however, the trough or troughs are automatically rotated on their bearings toward a horizontl or upright position so that a larger quantity of lubricant -will be retained therein. Consequently, as

the speed of the engine increases a gradually Cii -fl O `-casing tangentially to the because ne connectm j mechanism is remeiy simule and compact c ructicn and can be eperated "with Very' little power t@onn siderable sami ein lubricant can ne elected since the quant ty supplied to the bearings automatically decreases as the speed is 'reduced. llhen the speed increased however, the vquant-ity of lubricant supplied is automatiealljfv increased to 'meet the in creased demand therefor. Although l have show n only one term of mechanism embodying' my invention', it is obvious that 'various changes 'Within the skill oi the me chanic maybe made therein without departing :trom the spirit et the inventien, provided the means set Ylorth'in the 'tcl lowing claims are employed.

l claim as my invention zl, Ein adjustable lubricating mechanism Ltor an engine comprisine)v an oil trough adapted to hold a predetermined quantity of' lubricant in its horizontal or upright position and means controlled by the engine speed :tor rot-ating said trough so as to varjT the capacity thereof as the engine speed varies.
